Я использую sqoop 1.4.4 для передачи данных от оракула к Hive, используя фразу:sqoop 1.4.4, от оракула к улью некоторого поля в нижнем регистре, ERROR
sqoop job --create vjbkeufwekdfas -- import --split-by "Birthdate"
--check-column "Birthdate" --hive-database chinacloud --hive-table hive_vjbkeufwekdfas --target-dir /tmp/vjbkeufwekdfas --incremental lastmodified --username GA_TESTER1 --password 123456 --connect jdbc:oracle:thin:@172.16.50.12:1521:ORCL --query "SELECT \"Name\",\"ID\",\"Birthdate\" FROM GA_TESTER1.gmy_table1 where \$CONDITIONS" --m 1 --class-name vjbkeufwekdfas --hive-import
--fields-terminated-by '^X' --hive-drop-import-delims --null-non-string '' --null-string ''
это Безразлично» т работы, вызывают проверку использования sqoop стратегии в tool.ImportTool

Однако, если я не использую двойные кавычки:
sqoop job --create vjbkeufwekdfas -- import --split-by Birthdate

нуль-строка «»
Оракул ошибка собирается бросить, потому что поле имеет некоторые строчные буквы:
